So we are excusing this just because is Larian? Interesting... Specially with all those Outrage Videos about Blizzard, EA, etc... and how this was the Second Coming of Christ of Releases in the Videogaming Industry while Larian just swept this under the Rug. Of course anyone would want the Game to be finished but i don't know how to feel about them now...
I'm 100% with you on this, i called people out for the same thing in another thread like this one which got locked due to bickering.
How can people sit there and just think " This is fine " they lied to us, they advertised things that should of been in the game like the playable upper city, it's literally in one of their update blogs and they just removed it without so much as a word, potentionally breaking numerous companions in the process (noticably dooming Karlach to terrible endings), the 17000 variations which was supposed to come via the epilogue isn't a thing as well.
Well, I don't think that this is fine at all, but it is what it is...descision to cut lots of important stuff is a serious descision, if they decided to do it, then, probably, situation wasn't so trivial as you might think.
You also can't say that they could easily delayed release for 3 or even more months, you don't even know how much time they really need to completely finish what they planned nor you don't know their financial status & other issues.
I'm not saying it's ok, they promised one thing and delivered another and I'm dissapointed not less then you, but I'm saying that we don't know their problems and they are not idiots, you know, if they decided to cut so much content instead of delaying release, then they probably got a serious reason to do so, yet it's still a great game with a great replayability and I'll gladly play it again and again when they release Definitive Edition which, hopefully, will include at least the most important content they decided to cut.
